The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking to procure three circuit card assemblies for repair and modification purposes. The procurement involves a specific National Stock Number (NSN 7H-5998-016040221) and is limited to one source due to the government's lack of ownership of the necessary data for competitive procurement, which has been deemed uneconomical to acquire or reverse engineer. Interested parties have 45 days to express their interest or submit proposals, with the understanding that the government retains discretion over whether to pursue competitive procurement based on the responses received. For further inquiries, interested vendors can contact Stephen A. Knox at (717) 605-6805 or via email at STEPHEN.A.KNOX.CIV@US.NAVY.MIL.
